php is vulnerable to cross-site scripting (XSS). The vulnerability exists as a numeric truncation error and an input validation flaw were found in the way the PHP utf8_decode() function decoded partial multi-byte sequences for some multi-byte encodings, sending them to output without them being escaped. An attacker could use these flaws to perform a cross-site scripting attack.
